The people's crossover is the 2020 Volkswagen ID Crozz

The world's largest auto maker by sales plans to invest a total of 20 billion euros (24 billion USA dollars) until 2030 in electric mobility and even 50 billion euros in batteries.

The German automaker plans to invest more than £18 bn pounds into the venture for zero-emission cars, with 80 new-electrified models by 2025 - 30 of which will be plug-in hybrids and 50 pure electric models.

"We have understood and we will deliver", VW chief executive officer (CEO) Matthias Mueller said. "The transformation in our industry is unstoppable".

"There will be a coexistence between internal combustion engines and electric drive systems for a certain period", Mueller said to the BBC.

VolkswagenVolkswagen first introduced the ID concept during the 2016 Paris Motor Show.

Automakers will be eager to show off technologies that can help people get around without owning a auto. Automakers "won't be shouting about it, but diesels will be part of their lineup", says Ian Fletcher, principal analyst at IHS Market.

Carmakers are spending heavily to develop and improve electric cars to meet increasingly tough government regulations limiting air pollution. German automakers are taking this chance to show off the fruits of their push toward electric vehicles.

Volkswagen (VW), for its part, said it was seeking new global supplier contracts to source €50 billion ($60 billion) of electric auto content including batteries, which are not yet manufactured competitively in Europe.

According to Mueller, the group will require more than 150 gigawatt hours of battery capacity annually by 2025 for its electric vehicle fleet - the equivalent of four "gigafactories".

Over the previous year, it's unveiled three different Volkswagen ID electric-car concepts, two of them thinly disguised versions of future production models for 2019 and 2020.

Yet the Frankfurt show remains a very big deal for the home team: Daimler AG's Mercedes-Benz luxury brand, Munich-based BMW AG, and Volkswagen, all of which will have giant display stands. Looking to expand into the European market, Hyundai Motor and Kia Motors have unveiled new sub-compact crossovers and high-performance vehicles at the show. He added that VW is setting the scene for a final breakthrough in e-mobility.
